J-Kem® Temperature Controllers

An ideal controller for applications that don't require the precise regulation of the 200-series controllers. This controller is sufficient for 51 heating mantles, many ovens and other laboratory devices.

An ideal controller for applications that don't require the precise regulation of the 200-series controllers. This controller is sufficient for 51 heating mantles, many ovens and other laboratory devices. Contains a 100 hour digital timer to turn heating OFF (or ON) when the time expires.

J-KEM® Scientific's microprocessor based temperature controller. This model is J-Kem's most compact research grade controller, yet packed with 1200 Watts of power. Sufficient for heating mantles up to 5 L in size and most laboratory ovens and hot plates, valves, reaction blocks, etc.

J-Kem's microprocessor based temperature controller. A patented 8-bit computer adjusts power to the heater 2048 times per second permitting accurate control on small scale reactions. The Model 250 has 3 power outlets for maximum versatility in research. Two of the outlets are used for heating up to 1800 Watts. The third outlet (360 Watts), used normally for cooling, is programmable to provide power below, above or at the entered temperature. The third outlet can be used to turn on an alarm for an over or under temperature condition. Controller has the ability to display temperature without heating. The Model 250 controls temperature to within ±0.1°C of liquids for 1 ml to 5 liters. Available with a choice of Type "T" or Type "J" thermocouple. Complete item consists of: Controller, PTFE coated 12" long thermocouple, 10' coiled thermocouple cord, and 14/20 PTFE thermocouple adapter.

This temperature controller features two temperature controllers in a single cabinet to regulate two independent reactions. The Gemini features high powered outlets and a 100 hour digital timer to turn heating OFF (or ON) at a selected time. Features include over-temperature shutdown circuits with audible alarms, dual temperature displays, selectable operating modes, double fused and 100% solid state design. Contains J-Kem's patented power control computer which provides 0.1°C regulation of anything.

Designed for processes requiring an extra measure of safety. The Model 260 disconnects out put power if the process temperature exceeds the set-point by a user-specified amount, or following recovery from a power failure. Power remains off until the controller is manually reset. Over temperature is signaled by an indicator lamp and audible alarm. Provides for 0.1°C regulation.

This compact unit contains the equivalent of four Model 210 temperature controllers which allows four independent reactions to be run at the same time. Each channel packs 1200 Watts of power, over-temperature circuits and independent digital displays.

The only temperature controller available with a built-in independent back up controller to guard against heating accidents from equipment failure. The desired temperature is entered into the main temperature controller's digital meter which regulates heating. A high temperature cutoff is then entered into the backup limit controller meter. If the reaction reaches the high temperature limit, power is turned off to the heater until the controller is manually reset. Both meters independently monitor the reaction temperature.

The HCC controller line is designed to power large scale equipment up to 100 liter heating mantels. Built with the same uncompromised commitment to safety as our Model 270, the HCC series is available in 3 models for 120 or 230 volt operations. This controller also incorporates a 100 hour timer to turn heating OFF (or ON) when the time expires. The HCC controller line is designed for easy customization to meet unique research or additional safety needs.
